Tech Xplore / Brief physical access may let attackers alter Boeing 737 flight instructions
Physical access to an aircraft has not typically been considered a cybersecurity risk—but it should be, according to a team of computer scientists at the University of California San Diego. In a paper presented Aug. 13 at ...
Phys.org / Uniaxial strain reveals new way to tune electron flow in altermagnet material
Altermagnetism is a new, third type of magnetism of great interest for spin-transport applications like computer memory. If properly harnessed, it could combine the benefits of the two existing types of magnetism, ferromagnetism ...
Tech Xplore / Simple robot design exceeds human hand in some core motions
The human hand is a dexterous and versatile machine. Scientists have conventionally tried to replicate these traits in robots by copying the biological mechanics of the hand, resulting in complex and difficult-to-control ...
Tech Xplore / Levitated spinning device could help navigation when GPS is unavailable
Researchers at the A*STAR Quantum Innovation Center (A*STAR Q.InC), part of the Research, Innovation and Enterprise (RIE) Flagship in Semiconductors, have developed a levitated, millimeter-scale rotor that continued spinning ...
Phys.org / Tracer exchange reveals ions can speed up or slow down inside battery solids
Understanding how ions diffuse in solid materials is essential for technologies including batteries, electronics and chemical catalysts, but it has been hard for a simple reason: the materials are solids.
Phys.org / Satellite data reveal tropical forests respond differently to climate across continents
Satellite images can be used to estimate how much carbon forests store as aboveground biomass (AGB) and how biomass varies in different forests. In a study published in the journal Nature, a team of researchers affiliated ...
Tech Xplore / How malicious SIM cards can hijack smartphones, EV chargers and connected devices
Subscriber Identity Modules (SIMs), secure elements used to connect devices to a mobile network, can pose severe security risks when compromised. A malicious SIM could allow attackers to gather information about a device, ...
Phys.org / Trapped gases in ancient rocks challenge global explanation for 2-billion-year-old carbon anomaly
Roughly 2.5–2 billion years ago, Earth's surface experienced the biggest chemical change in its history when oxygen became abundant in the atmosphere, eventually leading to the evolution of complex life forms such as plants ...
Medical Xpress / Waist size is a powerful indicator of health risks, researchers find
Measuring waist size may be one of the simplest and most effective ways to detect obesity-related health risks, according to a study by Rutgers Health researchers.
Phys.org / A magnetic path to lower-power computing
From smartphones to data centers, modern electronics rely on billions of tiny switches that consume electricity every time they turn on or off. As global demand for computing continues to grow, so does the energy required ...
Medical Xpress / Ketamine and psychotherapy show promise as a combined approach to chronic neuropathic pain
Combining ketamine and psychotherapy is a safe and feasible approach with promising benefits for people experiencing chronic neuropathic pain, according to a new study by researchers at St. Michael's Hospital, the University ...
Phys.org / Severe weather now a key predictor of where bird species occur in North America
Scorching heat waves, severe cold snaps and other extreme weather events are limiting where species can exist—and affecting biodiversity estimates—for more than 500 North American bird species, according to a new, Yale–led ...
